Deer Valley President's Day W/E

going to be in Park City President's Day W/E and want to hit Deer Valley one day to try to get away from holiday crowds. Can anyone tell me how far in advance the DV daily ticket limit usually kicks in? Couple days? week or two? more?

Usually just a couple days, or the day before. You can also reserve purchase a ticket in advance so you are "in." My recommendation is go for Sat as that is when PCMR and Canyons will be swamped, so experience will be better at DV.
